The Grind King: Starting with One Hundred Thousand Sword Swings

Jiang Nan transmigrates to another world and binds the Grind King System from the start. Others cultivate through talent; I cultivate by grinding until I'm bald. While everyone discusses the rise of geniuses, I silently finish today's hundred thousand sword swings. The Demon Venerable has emerged? Hold on. Let me finish this daily quest before I go suppress him. Years later, the Three Realms tremble as they discover that the legend who keeps them awake in terror is actually a hardcore grinder who never sleeps.
